Remote radiocontrol



32 Claims.

My invention relates to a new method of anni apparatus fof tolling adio and simile? appaatus, simply by actuating a push button or switch, situsted either locally or remotely in i'elation to the radio set, till the tlesiiecl station is heard, when the button or switch is Ieleased, pemittircg the desired program to continue.

purposes of this invention are, to contoi radio set by just one button or switch, to permit elcleiiy people, children, or folk with poos eye sight to tune izo favorite stations, to contol a set that is out oi the Way, fiom one ci: mote posi tions, and to have a remote control that can be easily attached to a present tedio.

At the extremity of armature lli is contact ifi adapted to contact with contact i5 'to autow matically close circuit 16 connected to tile radio set and current supply thereof, when 'lectromagziet 9 attracts armature l0 releasing iction pad l2 from notch l@ in drum l. The coil 8 and the electromagnet 9 are connected in parallel., ami electric current from lines 1'? and i8 is coan trollecl oy the key or switch 19. The circuit i6, connected to the radio set and current supply thereof, is automatically 'closed when key i9 is actuated, energizing eleetromagnet 9 to attract armature l@ carrying friction paci l2, thereby reieasing drum l, which may loe calibrated as at 20. to iotate, and consecutively time in the radio stations. 2i indicates a Visual lamp indicator to indicate when current to radio set is on.

The mode of operation is moie particularly as iolloWs:-

A remote contirol radio as embodied .in my in vention is affixed to the tuning mechanism. oi" a radio set and the button or switch 'i9 ci" a 'plum iality ci" them, are connected paiailei, and

placed in convenient posities?, away iiom the as for instance, in adjacent When the button of switch 19 is actuated, electromagnet attracts armatue i9, pulling away :rictioioal pad i2 imm iiotcia l, .releasing diai l, closing ciicuit i6, which remains closed while :friction pad l2 is out of iiotcix i, 'time connecting tice current to tne radio set tif'iiic'i'i is indicated by illumination the pilot iam 2l.. At the .same time the attirent flows the heating coil 8, which is connected in paiaL- lei. to electromagnet 9. theieiiy heating causing the thermostatic haar i to veiy slowly cure/e to jioositioii^ as iodio teli We. Tile seam mental gear 3, pivoteci at sition indicated by E, is tous very slcitily actu" ated by the very slowly' co'fviiig thei'iiiostatic 'oai' E', inteiiiieshing with v secured to dial i, thereby vey slowiy iota-log dial i, and. eoiisecutively tuning iii the radio statioif'. when the desired station tit-.tten ci. switch is opened ami c desii'efi piogam continues. in. opening button. or switch the cmrre'nt is discontinued both from the heating coil i3 am?. tile electromagnet 9. Immediately esmatuice l@ tean sinned icy spring i3, is released by electioieagnet 9, and. the friction pad i2 grips the peiripicesy of dial i, vtlilis securely keeping' dial the position to smic it has been set, While thei'mo static 'oaf l returns to its normal sha-pe acti position..

Ali this time coiitaots .lli and 1.5 ai'e coi'itaeti ad lamp 2l ls lighted, indicating the." o1 remt tc the iadio set is on (circuit itil. s only when fiiction @ad l2 is in notch i that 'the cus rent to the radio set is 0H, anni the oiiligiiteii iamp 2l. so indicates.

After hearing the t station iol awhile sitem pose another station is desired. Button or switch i9 is again closed. immediately electomagmet 9 aga-in attracts armature ieleasine; the pee riphery of dial i the friction paci i2. @il the instant, geav 5i, which. tiiiu il nas been in fixed position by the migo ci? friction 'pecl l2 01o t e periphery oi diai i., returns to its origin nal position under tension of spring .causing diei i to do likewise.

The themiostatlc Tear 'l new begins to very slowly curve again, 'the dial i again very Slowly rotates, consecutively tuning in the radio stam tions till the desired one is heard, button oi switch i9 is opened, the desired continues.

After seifezai pi'ogiams have been anti one desiies to close the i'aclio, 'cotton or etait-cli.

brom the foregoing it will be readily observed that by simply manipulating a button or switch, ,positioned locally or remotely in 'relation to a radio set, a radio set is started and stopped, and any desired station may ce tuned in.

This remote radio control device is also much cheaper and simpler to manufacture and insta'ii than any remote control devices commercially sold at present, which employ expensive and bulky geared motors and auxiliary mechanisms and apparatus.

it will be understood that various inodica 'tions .may be made in the construction and ai rangement of parte without departing from the spirit oi the invention as claimed.
